This is the horrific moment a man was electrocuted after scaling a pylon ahead of a speech by suspended Brazilian president Dilma Rousseff.

The unnamed victim, who was wearing just a pair of beach shorts, appeared to grow more and more animated as supporters warmed up the crowd for the female politician at a political rally in Aracaju in the northern state of Sergipe.

After spending several minutes clinging to the pylon and waving a flag, he ignored warnings from bystanders to get down and climbed further up the pole towards the danger area where the electricity cables were attached.
